Question

the angle which is three times of its complimentary angle

Answer 1

hi mate☝☝☝☝☝☺☺❤❤

.let x be that angle, y its supplement and z its complement.
y= 180 - x and z= 90 - x 
the supplement of x is three times its complement, so y=3z
180 - x = 3( 90 - x)
180 - x = 270 - 3x
- x + 3x= 270 -180
2x= 90
x=45. 
so the answer is 45

Answer 2

.ʟᴇᴛ x ʙᴇ ᴛʜᴀᴛ ᴀɴɢʟᴇ, ʏ ɪᴛs sᴜᴘᴘʟᴇᴍᴇɴᴛ ᴀɴᴅ ᴢ ɪᴛs ᴄᴏᴍᴘʟᴇᴍᴇɴᴛ.
ʏ= 180 - x ᴀɴᴅ ᴢ= 90 - x 
ᴛʜᴇ sᴜᴘᴘʟᴇᴍᴇɴᴛ ᴏғ x ɪs ᴛʜʀᴇᴇ ᴛɪᴍᴇs ɪᴛs ᴄᴏᴍᴘʟᴇᴍᴇɴᴛ, sᴏ ʏ=3ᴢ
180 - x = 3( 90 - x)
180 - x = 270 - 3x
- x + 3x= 270 -180
2x= 90
x=45. 
sᴏ ᴛʜᴇ ᴀɴsᴡᴇʀ ɪs 45
